Near Lake Merritt, in the heart of downtown Oakland, the new 23-story residential tower joins the city skyline. Perkins+Will invited Integral Group to participate in an integrated design approach for the high-rise, with the goal of creating a new “vertical neighborhood” in the city with 206 residential units over ground-level retail.
Integral Group provided mechanical, electrical and plumbing design, as well as technology and architectural lighting design services. The collaborative design process with the architects allowed us to maximize the use of passive design features in the overall shape, size, and orientation of the building. This effective architectural massing, along with the building’s energy-efficient façade, will significantly reduce energy use in the building and allow it to achieve LEED Gold certification.
The building uses its water tanks, which are required for fire prevention, as thermal energy storage (TES). TES allows the building to run the cooling equipment during off-peak hours when the energy produced by the utility companies is cleaner and less expensive. At night, the high-efficiency air source heat pumps (ASHP) cool the temperature of the water in the tank, where it is then drawn upon during the daytime to cool the building. Integral Group also designed the building’s ASHP system to provide simultaneous heating and cooling throughout the building, as well as to be able to intelligently transfer heat between adjacent spaces within the building instead of just exhausting it.
